Aside from flicking the autopilot on, that’s all there is to it really. The majority of a true airline flight experience would be getting the plane set up for flight whilst on the ground, getting it in the air and following a SID (Standard Instrument Departure) which would see you abide by any restrictions in place (altitude, speed etc) and then it’s pretty much autopilot all the way until 1000ft above on approach, typically. Anyway, I’m waffling!
I agree with what you’re describing as your experience - I don’t think an airline experience is appropriate for someone that wants to have a go and a lot of these places get it wrong by setting up a short flight. If I was to run something similar I’d have the person take off and perform circuits around the airfield as I think you’d get way more from that than flying from a to b.
